Filed: 1998-09-28
Abstract: PROBLEM TO BE SOLVED: To provide an optical amplifier low in cost, simple in configuration and capable of realizing the gain equalization of a wavelength multiplex optical signal and the suppression of a noise light by a single optical device and to provide the wavelength multiplex transmission system using the optical amplifier. SOLUTION: This optical amplifier 10 is composed of an optical filter 4 with a periodic loss wavelength characteristic corresponding to a gain wavelength characteristic of an EDF 1 to a conventional optical amplifier provided with the EDF 1, a stimulation light source 2 and a synthesizer 3. The optical filter 4 has a characteristic where an interval (FSR) equivalent to one period of a loss wavelength characteristic corresponds to a gain peak wavelength difference of the EDF 1' and a maximum loss wavelength is nearly coincident with a gain peak wavelength toward the long wavelength of the EDF 1. This optical filter 4 applies gain equalization to a signal light placed around the gain peak wavelength toward the long wavelength side and a noise light produced around the gain peak wavelength towed a shorter wavelength is suppressed.

Title: Corrosion depth judging jig of lp gas container
Inventor: KURIBAYASHI ISAO
IPC: G01N21/88
Filed: 1985-12-03
Abstract: PURPOSE:To make it possible to cope with many kinds of LP gas containers, by making it possible to easily re-adjust an indicator to zero scale even if the radiuses of curvature of the mirror plate parts of the LP gas containers differ. CONSTITUTION:In a configurational part approximate to a corroded mirror plate part 4, if a push rod 20 is pushed to the direction shown by an arrow R while three support legs 23 hold a main body 1 so as to be contacted with the mirror plate part 4, the inside 21a of a hook 21 pushes a lever 13 to move the same in a circular arc state. Therefore, a lever 8 also moves in a circular arc state by the frictional resistance of a seat plate 12 but impinges against a stopper 27 on the way to be stopped. However, if the push rod 20 is further pushed, sliding is generated and only the lever 13 moves. Next, if the push rod 20 and the hook 21 are returned to their initial positions by utilizing the repulsive force of a compression coil spring 22, the inside of the hook 21 allows the lever 13 to move to the direction shown by an arrow S in a circular arc state. At this time, the end part of a lever 6 cooperated through a lever 8, a pin 9 and a fulcrum shaft 5 presses a pin 3 to the side of the mirror plate part 4. Hereupon, the circular arc movement of the lever 8 stops but the lever 13 continues circular arc movement by a sliding phenomenon and stops along with the hook 21 to set the position of an indicator 17 at this time to a zero scale.

Title: Mis type semiconductor memory device
Inventor: NAKAMURA KUNIO
IPC: H01L27/10
Filed: 1986-11-17
Abstract: PURPOSE:To prevent the generation of short-circuit accidents among word lines by a residue layer of a second layer polycrystalline silicon layer by dividing a first layer polycrystalline silicon layer into blocks and forming it so as to be isolated at every memory cell in the direction of bit lines and so as not to simultaneously cross two or more of adjacent word lines in the direction of word lines. CONSTITUTION:A first layer polycrystalline silicon layer forming a capacitance electrode is isolated into blocks and shaped so as to be isolated at every memory cell in the direction of bit lines 7a, 7b as shown in 4a and 4b and so as not to simultaneously cross adjacent word lines in the direction of word lines 6a-6d. Since the first layer polycrystalline silicon layer is parted between adjacent two word lines, a residue layer generated when a second layer polycrystalline silicon layer is shaped after a pattern to 6a-6d is also brought to a mutually divided state as shown in 10a and 10b. Accordingly, short circuits among word lines by the residual layer in the second layer polycrystalline silicon can be prevented.

IPC: G11B11/10
Filed: 1989-10-24
Abstract: PURPOSE:To prevent the deformation of a recording medium by providing means for moving the medium which move in a radial direction in synchronization with the movement of an optical head and negate the pressing force acting from a head side on the medium surface in the positions opposite to the head on both sides of the medium. CONSTITUTION:A spring support 5 is moved in the radial direction of a disk 1 in accordance with the control signal to a driving device 4 to control the movement of a floating body 6 to the prescribed back of the head. The body 6 is made of alumina ceramics and has tapers 61, 62 on the bottom side and an air relief part at the center of the bottom surface. The same control signal as the control signal of the driving device 4 is inputted to a driving device 31 of a pressing means 3 and a floating base material 36 of the same size as the size of the body 6 is moved via the spring support 32 in the radial direction in synchronization with the head 2. The working pressures acted by the base materials 6, 36 on both sides with the disk 1 in-between are offset and the deformation of the disk 1 is prevented. The floating traveling of the head 2 is, therefore, stabilized and the light of a laser 7 is surely converged to the convergent surface of the disk 1. The malfunction of the recording is thus prevented.

Title: Overlapped video signal display device
Inventor: NAKATANI MITSUYOSHI
IPC: G09G5/36
Filed: 1991-10-23
Abstract: PURPOSE:To make display of video signal on which image data is overlapped at high speed. CONSTITUTION:A video signal write means 6 does not access an overlay memory 1 but access a memory means 5 when it reads out video signal selecting information to select video signal to be written in a frame memory 2. A time for access to the overlay memory 1 is occupied by image data to be input only. Next, a temporary holding means 4 holds temporarily the video signal selecting information contained in the image data. Thus, even when the video signal selecting information is read out from the memory means 5, writing processing of the image data into the overlay memory 1 is made continuously because the video signal selecting information is taken out from the image data to be input.

Title: Low-melting point glass paste
Inventor: TAKEUCHI YUKIHARU
IPC: C03C8/16
Filed: 1985-12-07
Abstract: PURPOSE:To obtain the titled low-m.p. glass paste capable of forming a semiconductor package of high value as a commodity and capable of obtaining a low-m. p. glass layer without any air bubbles and without being blackened by dispersing low-m.p. glass powder in a specified solvent contg. a polymerization inhibitor. CONSTITUTION:Low-m.p. glass powder is dispersed in a solvent obtained by mixing terpineol and >=0.1wt%, based on the terpineol, of a polymerization inhibitor (e.g., hydroquinone) to form the low-m.p. glass paste. Although a solvent contg. terpineol has been used heretofore, the solvent is changed in part by oxidative polymerization, etc., when dried and remains as the evaporation residue, the residue is decomposed in the glass when baked, hence air bubbles are generated, and the residue is carbonized to blacken the glass. A low-m.p. glass layer without any above-mentioned defects can be formed by mixing the polymerization inhibitor into the solvent. Consequently, a semiconductor package, etc., which are highly valuable as a commodity can be produced.

Filed: 1995-10-24
Abstract: PROBLEM TO BE SOLVED: To effectively prevent generation of a fuel cut hunting phenomenon by providing a deceleration correction means which sets a fixed deceleration command given by a deceleration command means to a value different from an ordinary value when the fuel cut hunting phenomenon is detected. SOLUTION: When a vehicle travels on a descending slope road surface by a constant sped traveling mode, a throttle is actually throttled substantially to a fully closed condition, and constant speed traveling control can not be performed unless an engine brake is applied.
